Normally at the beginning of the therapy the sessions are weekly. This permits to secure the therapeutic relationship and the trust on the therapist (therapeutic alliance) as well as to carry out a detailed evaluation. This will a result in a faster and most effective intervention on the initial phases of the therapy. When the clinician observes that there is improvement and he considers than the person has gained stability, the sessions normally will take place every two weeks, although this depends on the progress of the individual case. Thus, as the person recovers, the sessions will be less frequent and will have the aim to follow up the improvements and to reinforce them. The clinical psychologist will suggest to end the treatment once the therapeutic aims have been achieved.
